Two companies linked to China's Zhangjiagang Oceanicwit Shipping have asked the High Court of Singapore to enforce a purchase deal for open-hatch bulker whose delivery, they allege, was subject to delay.

The details of the request by Morning Swan Shipping and Dina Ocean Shipping, over their October 2017 purchase for the 30,800-dwt Alkar Trust (built 1997) for $3.87m, emerged after TradeWinds reported last week that they had seized the vessel.
